The Challenge CLR03 road bike has been designed in conjunction with the experts at Cycling Plus and Bikeradar using the best quality components and a bespoke frame design. The aluminium frame features butted tubing for extra-lightweight manoeuvrability, making it even easier to cycle uphill: paired with a carbon-fibre front fork and a 16 speed Shimano Claris gear system, the CLR03 is a sophisticated ride. Powerful calliper brakes and double-wall aluminium wheels complete the effect. Perfect for commuting through cities and towns this bike gives you the power you need to tackle flat roads or challenging hills. It is also great for leisure rides or as part of an exercise and fitness regime. Alloy frame. 16 gears. Shimano shifters. Shimano gears. Front calliper and rear calliper brakes. Rigid suspension.
